Market Basket employees had walked off the job not for better pay or benefits, but solely because they wanted their boss back. The standoff ended with Demoulas’ reinstatement.

Producer Nick Buzzell says he was “blown away” by the walkout. Actor and Massachusetts native Michael Chiklis narrates the film.
